A fusion safety experiment was conducted to determine the consequences of water injection into high-temperature lithium-lead alloy under postulated reactor accident conditions. The temperature and pressure response, fraction of water reacted, quantity of hydrogen produced, and behavior of radioactive species associated with the use of this alloy as a breeder material were determined. The reaction products were identified and the aerosol was characterized for particle size, chemical composition, and deposition rate. The water injection was shown to be self limiting for a blanket module designed to withstand the pressure of the water coolant. Radioactive doses associated with the aerosol release from a high-temperature alloy breeder module were determined to be several orders of magnitude below the dose limit for acute health effects. The results were compared to previous experiments and recommendations were made.
